In trigonometry, the secant function, commonly abbreviated as sec, is the multiplicative inverse of the cosine function. In other words, sec refers to the ratio of the hypotenuse to an adjacent side ...

How to Graph a Function in Excel. A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a ...
